I have 17 old AA rechargeable batteries and would like to figure out the fastest way to know which AA batteries are at the end of their recharging life.
Currently, I am putting each AA battery into my rechargeable computer mouse, fully recharging the battery and then using the mouse. So far, two batteries have died after 8 hours of mousing. I am currently working on my third battery.
I have a multi-meter and a wall charger. How can I figure out which batteries are at the end of their recharging life quickly?
With regular one-use batteries, I can use the multi-meter to test the voltage. If the voltage 0.2 V below the battery's rated voltage, then I throw the battery away. Would the same work for a rechargeable battery?
